#3 It uplifts the star power of the match, which would result in more PPV buys
WWE has booked Survivor Series brilliantly, with Goldberg vs. Brock Lesnar at the helm, their approach caters more to mature fans. Shane’s presence would further their cause, as seeing, the two seasoned veterans (Goldberg and Shane), would be reminiscent of the good ol' Attitude Era days.
While Survivor Series might already be a sold-out show, Shane’s association with Team Blue could boost PPV numbers on the WWE Network. It has been noted that WWE Universe responds positively to a returning star.
If WWE structures the upcoming SmackDown Live, surrounding the idea of Shane making a return, it could prove climacteric to the success of Survivor Series by generating more demand for PPV buys. This institutionalises a strategic victory for the WWE.
